WARP-DYEING APPARATUS.

Original application Med December 5, 1922, Serial No. 605,032. Divided and this application filed September 29, 1923.

To all whom it may concern:

Be it known that we, HAROLD MASON 'CEAsE and GEORGE Wnnror ROBERTSON, citizens of the United States and residents of Danville, in the county of Pittsylvania and vision of our application Serial More especially our invention has to do with the continuous dyeing of warps or in other words to "a machine wherein the dye is maintained in approximately full strength then reverse improved dyeing machine, and,

by the intermittent or regular addition of dye stock as distinguished from those in.

- which the warps gradually use up the dye in the first assage therethrough and are d and passed through a second dyebath in order to render their color uniform throughout, our primary object being the provision of a dyeing machine by means of which uniform results may be easily obtained in a continuous run apparatus.

It is for the above reasons that our inlvention proposes the successive dipping of the warps in'the same dye chamber in such manner that they are subjected to the same dye liquid at each di andv are oxidized to render the dye insolu le after each dip.

In the accompanying drawings, illustrating our present invention and forming a part of this specification,

Figure 1 1s a sectional side view of our igure 2 is a top. lan view thereof. According to our 1nvention, we provide a dye vat 15, downwardly into which at one rope. warps pass end the warps pass in practice around "a" guide roller 52 and it is to be particularly noted that this dye vat has a single internal compartment provided with two sets 53 and 54 of internal warp guide rollers. As the downwardly into one end of the tank they roceed to the lower end of the set 53 of gulde rollers and have a circuitous path around these rollers and up- Serial No. 665,722.

wardly through the dyestufl', the latter being in constant agitation and circulation by aseries of agitators 55 in the form of paddles secured upon transverse shafts 56 whose opposite-ends project beyond opposite sides ofv the vat. These shafts 56 have at one side of the vat sprockets 57 connected by sprocket chains 58 so that the several shafts 56 with their agitators 55 rotate in unison, the shaft 56 near the intake end of thevat having at its opposite end a sprocket 59 around which the lower end of a sprocket chain 60 extends.

.After their circuitous travel around the guide rollers of the first set 53 of the dye vat, the rope or chain warps pass around a guide roller 61 and between squeeze rolls 62, of which the lowermost roll has a gear 63 engaging the gear 64 of a oountershaft 65, this countershaft having a sprocket 66 around which the upper end of the agitator driving chain 60 extends, and is also provided with a sprocket 67 around which a driving sprocket chain 42 extends.

The shaft of the lower squeeze roll 62 also has a sprocket 68 from which a sprocket chain 69 leads. Upon their passage between the squeeze rolls 62 where the surplus dye liquid of the first dip is removed, the warps pass upwardly and for a considerable space around oxidizing reels 7 0 during which the these guide rollers of the second set 5i and from the top of this set pass over a guide roller 72 and between squeeze rolls 73 of which the lower roll has a sprocket 7 4. driven by the sprocket chain 69 beforementioned. 'In this way the surplus dye liquid of the second clip is squeezed fromthe chain warps and these warps then pass upwardly for a considerable distance around oxidizing reels 75 and during such passage the dye accumulatedduring the second dip is oxidized and rendered. insoluble.

This completes the dyeing apparatus and it is to be particularly noted in connection :with the dye vat itself that we provide for two separate dips of the warps into the same dye chamber and the same dye liquid with the latter at all times in agitation and circulation through the use of the agitators 55, the warps passing between squeeze rolls and over oxidizingreels at the end of each dip so that by the intermittent or regular introduction of dye stock within the vat we insure uniform coloring of the warp without waste of dye stock and without the use of expensive apparatus which would necessarily be employed for maintaining separate dye vats in uniform condition with doubtful results.

Furthermore byproviding for successive dips of the warps in the same dye vat we have not only accomplished the advantages hereinbefore set forth from a mechanical standpoint, but we have furthermore rendered this operation certainly uniform which is essential to the success of a continuous apparatus of this nature. 2

We claim: 1. In a warp treating apparatus, a warp dyeing machine including a single dye chamber having means for separate, successive movements of warps therethrough, and having squeeze rolls and oxidizing devices for the warps after each movement thereof through the dye chamber.

2. In a Warp treating apparatus, a warp dyeing machine including a single dye chamber having means for separate, successive movements of warps therethrough, and having squeeze rolls and oxidizing devices for the warps after each movement thereof through the dye chamber, and means for continuously agitating the dye material in said dye chamber.

3. In a warp dyeing apparatus, a tank having a single chamber for the dyestuif, separate sets-of warp engaging rollers within said chamber, guide rollers on the tank for guiding the warps to said sets of rollers.

oxidizing reels over which the warps pass from each set of tank rollers, and squeeze rolls through which the warps ass from each set of tank rollers, as descri ed.
